TOOL-STOCK FOR IRO'ND-PLANERS.

SPECIFICATION forming part of Letters Patent No. 280,812, dated July 10,1883.

Application filed April 6, 1883. (No model.)

To all whom it may concern.-

Be it'known that I, WILLIAM GLEASON, of Rochester, in the county ofMonroe and State of New York, have invented a new and useful Improvementin Tool-Stocks for Iron-Planers, which improvement is fully set forth inthe following specification and accompanying drawmgs.

The object of my invention is to produce an improved tool-stock foriron-planers, by means of which various kinds of work required of saidplaners may be more readily and conveniently donesuch, for instance, asplaning the under surfaces of horizontally-projecting parts or ledges ofcastings. v

Referring to the drawings, Figure 1 is a front elevation of theswing-slide with screw, handle, and vertical slide, (the tool-holdingstock being o1nitted,) showing the annular groove and center opening inthe vertical slide; Fig.- 2, a side elevation of the same with thetool-stock and tool added, parts being broken away and other partsvertically and centrally sectioned, viewed as indicated 'byarrow in Fig.1; Fig. 3, a front elevation of a part of the vertical slide and thetool-box, the annular groove and center opening being shown in dottedlines; Fig. 4, a front elevation of the same, having the apron with theclampingbolts and returning-spring added, viewed as indicated by arrow 2in Fig. 2; Fig. 5, an outline figure, showing morefully the form of thereturning-spring, viewed as indicated by arrow 1 in Fig. 4; Fig. 6, afront elevation of the parts shown in Fig. 4, with the tool-stock turnedand adapted to plane an under surface, a proper tool being supplied, andthe returning-spring adjustedto bear upon the apron; Fig. 7, a view ofthe parts shown in Fig. 4, viewed as indicated by arrow z in said latterfigure, the swing-slide being horizontally sectioned on-the dotted linea; and Fig. 8, a detached portion of the seat for the tool-stock, drawIn to a larger scale, with parts sectioned, showing more clearly theannular groove or slot and hook-head of a bolt resting therein. Figs. 1,3, 4, 6, and 8 show the parts as being viewed from the same point ofobservation.

Referring to the parts, A is the swing-slide, provided with the V-waysl, screw B, handle 0, and circle D, all of usual form, said swingslidebeing secured in the ordinary way to the circle H of the crossslide ofthe planer by bolts passing through the holes in. The vertical slide F,adapted to move vertically in the V-ways of the swing-slide, is formeddifferently from the corresponding piece in other planers, in therespect that it is formed with a plane vertical face, I), only slightlyraised or projected from the bodyof the vertical slide, and providedwith an annular slot, a, and central circular opening, (I. The face 1)forms a seat for the tool-box G, the rear surface of the back plate, f,of which is'made plain tofit the surface I), and provided with a centralprojecting part, c, fitted to the opening (Z in the face I), as shown inFig. 2. By means of this .construction the tool-stock may be turned in avertical plane on the face or seat b, or have a swivel movement thereon.

The forming of the tool-stock separate from the slide F and attachingthe same thereto in a manner permittingit to have a swivel indvement isthe essential part of this invention.

Heretofore in planers the tool-box G and the slide F have been formed inone piece, the

former being only a forward horizontal eXtension of the latter.

The slot (0 is cut under on its inner periphery, as indicated by dottedcircle in Fig. l and shown more clearly in Fig. 8, and the toolboX G isheld against the face I) by means of hook-headed clamping-bolts Figs. 2and 8, having their heads m resting in the slot a, with the hook part ofthe head turned under the strong ledge h of the groove. These bolts passthrough holes in the back plate, f, of the toola box, and are providedwith ordinary screwnuts, 0, as shown in Figs. 2 and 3, four of whichbolts I prefer to use. To make room for the nuts 0 at the sides of thetool-box, and to permit a wrench to be used to turn the same,semicircular openings or slots 1' are formed in the part G, and openings1", for the same purpose, are formed in the rear surface of the apron K,as shown. The apron K rests within the tool-box in the usual manner, andis hung upon a'tapering pin, 1), upon which it may swing out to raisethe point of the tool from the work while the latter ismoving back or inthe direction indicated by the arrow 00 at the point of the tool.

The usual roughened surfaces, 01, clampingbolts 1, and clamps "u aresupplied to hold the tool b. By loosening the nuts 0 the tool-stock maybe turned around 011 the seat b to any desired position of adjustment,the heads m of the bolts sliding around in the slot a as the tool-stockis turned.

The tool-box G and apron K, with the clamping-bolts t and clamps 11,together constitute the toolstoek, all of which turn in a vertical planeupon the seat I), as above stated.

Fig. 6 shows the tool-stock as having been turned around through an arcof something more than ninety degrees to the left, and provided with atool bent to one side and adapted to plane the under horizontal surfaceof a projecting piece, I, which may be supposed to represent the lateralextension of the upper side of a lathe-bed or other similar casting. Byadjusting the tool-stock and tool to the position shown in said figure,and putting in operation the usual cross-feed of the planer, the undersurface of the piece L may be planed as conveniently as upper-surfaceplaning is done by planers provided with the old form of tool-stock.

In planing an upper surface in the usual manner, when the table of theplaner is moving back after a out has been taken, carrying the work inthe direction indicated by the arrow :0, the point of the tool will beswung forward and slightly raised, as above stated, by the work rubbingagainst the under surface thereof. After the work has passed the pointof the tool, the apron, from gravity, will drop back onto its bearingwithin the tool-box,brin ing the tool again into position to take thenext cut; but in planing an under surface it is clear that the toolboxwill not thus operate.

To insure the returning of the apron to its place within the toolbox atall times, when from its position it would not be returned by theactionof gravity, I employ a spring, .9, Figs. 4 and 5, secured to oneside of the toolbox in such a manner that its free end maybe adjusted tobear against the surface of the apron, as shown in Fig. 6. Now, if thetoolstock is turned around more than ninety degrees from a vertical, asshown in Fig. 6, the point of the tool. will. tend, from gravity andfrom the friction of the work rubbing against it while running back, todrop or swing away from the work. I employ the spring 8 as a means toprevent the point of the tool thus moving too far away from the work,and to insure its return. to position for each successive cut.

The bolts g are inserted in the slot a, at the rear side of the slide F,through a hole, 0, at the bottom of said slot, before said slide is putto place on the swing-slide, the hole 0 opening out through the backsurface of the slide F, as shown in. Fig. 7.

I claim as my invention- 1. In an iron-planer, in combination with thevertical slide F, provided with the vertical face or seat I), circularundercut groove 0r slot (1, and circular opening d, the tool-box G,having its back surface fitted to the seat I), and provided with aprojecting part, c, to fit the opening (I, by means of which saidtool-box may have a swivel, movement upon the slide F, with means tofasten said tool-box G rigid ly to the slide F,.substantially as shownand described.

2. In an iron-planer, the vertical slide F, provided with. the verticalseat I), undercut groove or slot a, central circular opening, (I, andopening (2 from the back surface of the slide F through to the bottom ofthe slot a, substantially as and for the purpose set forth.

3. The tool-box G of an iron-planer, fitted to a seat, I), upon theslide F, substantially as shown, jointly with clamping-bolts to hold thetool-box and slide together, the tool-box being provided with theopenings 27, in which to enter a wrench to turn the screii nuts 0,substantially as set forth.

l. The tool-box G of an iron-planer, provided with the returning-springs, in combination with the apron K, substantially as shown anddescribed.
